연구배경 : 주폐포자충은 HIV 감염자에서 폐렴을 일으키는 주요 원인인데, 최근에 면역 기능이 저하된 환자들이 중가하면서 HIV 비감염자에서 발생되는 PCP가 늘어나고 있다. 연구자들은 HIV 감염자 및 비감염자에서 PCP의 임상 양상을 비교해 보고자 하였다. 방 법 : 1996년부터 2002년까지 연세대학교 의과대학 세브란스 병원에서 PCP로 진단 받은 환자를 대상으로 의무기록을 후향적으로 조사하여 환자들의 연령, 성별, 기저 질환, 면역 억제제의 사용, 검사 소견, 임상적 경과, 치료 및 예후 등에 대하여 알아보았고, HIV 감염자와 비감염자의 임상 양상을 비교하였다. 결 과 : PCP로 진단받은 25명의 환자 중에서 HIV 감염자는 16명, HIV 비감염자는 9명이었다. HIV 감염자의 평균 연령이 ($41.0{\pm}9.6$세) 비감염자보다($47.7{\pm}17.9$세) 낮았으나 통계적 의의는 없었다. HIV 비감염자에서 동반된 기저 질환으로는 혈액학적 악성질환이 7예, 장기 이식 l예, 염증성 질환 l예 등이 있었다. HIV 비감염자 중 77.8%가 2개월 이내에 면역억제제를 복용한 적이 있었다. 방사선 소견은 HIV 감염자에서는 12예(75%)에서 PCP에 전형적인 양측성의 폐문 주위 간유리혼탁 소견을 보였는데, 비감염자에서는 4예(44.4%)에서 전형적 방사선 소견을 나타냈다. HIV 비감염자에는 치료를 위해 스테로이드를 같이 사용한 경우가 6예(66.7%)였는데, 감염자에서는 스테로이드를 같이 사용한 경우는 12 예(75.0%) 였다. 인공 호흡기 치료를 시행한 경우는 HIV 비감염자에서는 2예(22.2%)였고, 감염자에서는 6예(37.5%)였다. HIV 비감염자의 사망률은 11.1% 였으나, 감염자의 사망률은 50.0% 였다. 결 론 : PCP는 HIV 감염자와 비감염자에서 다른 임상양상을 나타내는 경향이 있었으며, 향후 HIV 감염자 및 비감염자에서의 PCP의 위험 인자, 치료 및 예후, 예방 요법의 적응 및 지침 등에 대한 보다 많은 예에서의 전향적인 연구가 필요하다고 생각된다.

The life expectancy of HIV-infected subjects has improved dramatically since the introduction of highly-active antiretroviral therapy (HAART). Considering that patients with HIV infection are living longer, treatment plans should include those for the accompanying co-morbidities such as cardiovascular diseases, metabolic syndrome, malignancy, etc. This review discusses the impact of HAART on the epidemiology of survival and co-morbidities (malignancy and cardiovascular diseases) among HIV-infected subjects.

Background: To study the prevalence of abnormal anal cytology by Papanicolaou (Pap) technique in HIV-infected women who attended a HIV clinic at Prapokklao Hospital, Chanthaburi, Thailand. Materials and Methods: HIV-infected women who attended a HIV clinic at Prapokklao Hospital from March 2013 to February 2014 were recruited for anal Pap smears. Participants who had abnormal results of equally or over "abnormal squamous/glandular cells of undetermined significance" (ASC-US) were classified as abnormal anal cytology. Results: A total of 590 anal Pap smears were performed at HIV clinic of Prapokklao Hospital during the study period. There were only 13 patients who had abnormal Pap tests, which were: 11 ASC-US and 2 HSIL (high grade squamous intraepithelial lesion). The prevalence of abnormal anal Pap smears in HIV-infected women who attended HIV clinic at Prapokklao Hospital was 2.2 percent. Percentage of high risk HPV in patients who had abnormal Pap test was 88.9 (8/9). Conclusions: The prevalence of abnormal anal Papanicolaou smears in HIV-infected women who attended the HIV clinic at Prapokklao hospital was quite low in comparison to the earlier literature.

Background: To date, no study has described disease progression in Asian patients infected with HIV-1 subtype D. Methods: To determine whether the disease progression differs in patients infected with subtypes D and B prior to starting combination antiretroviral therapy, the annual decline (AD) in $CD^{4+}$ T cell counts over $96{\pm}59months$ was retrospectively analyzed in 163 patients and compared in subtypes D and B based on the nef gene. Results: $CD^{4+}$ T cell AD was significantly higher in the six subtype D-infected patients than in the 157 subtype B-infected patients irrespective of Korean Red Ginseng (KRG) treatment (p < 0.001). Of these, two subtype D-infected patients and 116 subtype B-infected patients had taken KRG. AD was significantly lower in patient in the KRG-treated group than in those in the $KRG-na{\ddot{i}}ve$ group irrespective of subtype (p < 0.05). To control for the effect of KRG, patients not treated with KRG were analyzed, with AD found to be significantly greater in subtype D-infected patients than in subtype B-infected patients (p < 0.01). KRG treatment had a greater effect on AD in subtype D-infected patients than in subtype B-infected patients (4.5-fold vs. 1.6-fold). Mortality rates were significantly higher in both the 45 $KRG-na{\ddot{i}}ve$ (p < 0.001) and all 163 (p < 0.01) patients infected with subtype D than subtype B. Conclusion: Subtype D infection is associated with a >2-fold higher risk of death and a 2.9-fold greater rate of progression than subtype B, regardless of KRG treatment.

Toxoplasma gondii is an important opportunistic agent especially in immunocompromised hosts and can cause significant morbidity and mortality. Hence, detection and monitoring of anti-Toxoplasma antibodies are of a great interest in HIV-infected patients. A study on the prevalence of toxoplasmosis and associated risk factors was carried out among HIV-infected patients in Jahrom, southern Iran. The prevalence of anti-Toxoplasma IgG antibodies was 21.1% in HIV-infected patients by ELISA. PCR was performed on all of the samples, and 1 of the blood samples was positively detected. Among the HIV patients, anti-Toxoplasma IgG antibodies were significantly higher in age group of 30-39 years old (P=0.05). The seroprevalence of toxoplasmosis in patients with $CD4^+$ < $100cells/{\mu}l$ was 33.3% that was significantly higher than the other groups (P=0.042) with or without IgG antibodies. The $CD4^+$ count mean of seropositive patients was lower than that of seronegative patients. The seroprevalence of toxoplasmosis in patients with highly active antiretroviral therapy was significantly less than patients without therapy (P=0.02). In conclusion, this study showed low seroprevalence of latent toxoplasmosis among HIV-infected patients in the region and confirmed the need for intensifying prevention efforts among this high-risk population and also the risk of toxoplasmosis reactivation which could be important among this population.

Background: Tuberculosis (TB) is the leading cause of mortality among human immunodeficiency virus (HIV) patients and the majority of them occur in developing countries. The aims of the present study were to determine the frequency of HIV/TB co-infection and other probable associated factors. Methods: This 10 year retrospective study was conducted on 824 HIV patients in the south-west of Iran. HIV infection was diagnosed by the enzyme linked immunosorbent assay and confirmed by Western blot. TB diagnosis was based on consistency of the clinical manifestations, chest X-ray, and microscopic examination. Drug susceptibility testing was done by the proportional method on $L{\ddot{o}}wenstein$-Jensen media. Results: Of 824 HIV patients, 59 (7.2%) were identified as TB co-infected and the majority (86.4%) of them were male. Of the overall TB infected patients, 6 cases (10.2%) showed multidrug-resistant with the mean CD4+ lymphocyte count of $163{\pm}166cells/mm^3$. The main clinical forms of TB were pulmonary (73%). There was a significant (p<0.05) correlation between TB infection and CD4+ lymphocyte counts ${\leq}200cells/mm^3$, gender, prison history, addiction history, and highly active anti-retroviral therapy. Conclusion: We reported novel information on frequency of HIV/TB co-infection and multidrug resistant-TB outcome among co-infected patients that could facilitate better management of such infections on a global scale.

Purpose: Infection with HIV-1 virus has become a critical worldwide public health problem. The oral complications of HIV infection with its progression of impairment of the host response to combat infection present unique challenges to the periodontists. Material and Methods : Medline research was carried out to find relationship of the progression of HIV infection to the occurrence of oral lesions including the HIV-related periodontal diseases. Results: The linear gingival erythema, necrotizing ulcerative periodontitis, necrotizing ulcerative gingivitis and oral candidiasis are common lesions in HIV-infected individuals. The linear gingival erythema and necrotizing ulcerative periodontitis lesions in HIV-infected subjects were found to have a similar microbiological profile. There are several general considerations in the periodontal management of the HIV-infected patient with or without periodontal disease. The altered immunity and host response in patients with HIV infection may also affect the incidence and severity of other common forms of periodontal disease not associated with HIV infection. Conclusion: Periodontal diseases in HIV-infected individuals present unique challenges in diagnosis, monitoring, treatment and maintenance. Therefore exact HIV staging, geographic location, antiviral and antimicrobial therapies and oral habits should be taken into consideration when treating HIV-infected patients.

We have shown that long-term intake of Korean red ginseng (KRG) delays disease progression in HIV-I infected patients. In the present study to investigate whether this slow progression was associated with protective human leukocyte antigen (HLA) alleles as well as with KRG-intake, we have performed clinical analysis of 31 HIV-1 infected patients who have been living for more than 10 years without any antiretroviral therapy. Average amount of KRG-intake over $130\;{\pm}16$ months was $4,797\;{\pm}4,921\;g$ and the annual decrease in CD4 T cell (AD) was $30\;{\pm}29{\mu}L$. We observed significant correlations among amount of KRG-intake, AD(r=-0.53, P < 0.01), and plasma HIV-1 RNA copy (r=-0.35, P < 0.05), along with a significant correlation between KRG-intake and HLA score AD(r=-0.49, P < 0.01), whereas there was no significant correlation between HLA score and AD or viral load. When the 31 patients were divided into 2 groups based on the amount of KRG-intake, the $AD(14/{\mu}L)$ in the 16 patients who had taken higher amounts of KRG was significantly less than that $(49/{\mu}L)$ in the 15 patients with a little or no KRG-intake (P < 0.01). These data indicate that KRG-intake sig­nificantly slows CD4 T cell depletion in HIV-1 infected patients.

For 16 years after the finding of HIV as an agent of AIDS in 1981, HIV therapeutic drugs of reverse transcriptase inhibitors (AZT, ddI, ddC, d4T) and protease inhibitors have been developed. Recent studies also were focused on a combination therapy by using HIV therapeutic drugs or natural compounds. Korean red ginseng (KRG) of natural compounds has been well known as a good reinforcement agent in Asia. The percentage of CD3+CD4+ T cell in nine HIV-infected patients without KRG treatment averaged 17.8% on baseline and decreased 15.8% after 6 months, whereas the percentage of the cell in fifteen HIV-infected patients with KRG treatment averaged 15.3% on baseline and increased up to 18.9% after the same period. The average percentage of CD3+CD8+ T cell of KRG-nontreated and KRG-treated HIV patients increased after 6 months 47.8% to 50.7% and 44.7% to 51.4%, respectively; and the average percentage of B and NK cell in the KRG-nontreated and KRG-treated HIV patients decreased 9.4% to 7.9% and 13.0% to 9.7%, 8.9% to 8.5% and 16.2% to 11.6%, respectively. KRG, therefore, didn't have any effects on the CD3+CD8+ T cell, B cell, and NK cell. However, it seems that KRG has a potential activity for stimulatiing the CD3+CD4+ T cell and some inhibition on destroying of this cell with no significance.
